Patent DE-4039668-A1 (DE)
Title: Audio compression amplifier avoiding cut=off - achieves by input independent reference current inputs to multiplier
Inventor: KLEINE ULRICH DR ING
IPC: H04R25/00
Filed: 1990-12-12
Abstract: A compression amplifier of the type used in hearing aid equipment receives the input signal by a current-voltage multiplier (IV) coupled to a pair of amplifiers (V1, V2). A feedback network (RN) provides an amplitude dependent current (I2) for the multiplier. In order to avoid cut-off effects over a large dynamic range, the regulating current (I2) is superimposed on an independent reference current (IR). This, and a feedback reference (IR'), form a common reference operating point for the multiplier. ADVANTAGE - Copes with wide dynamic input. Can be integrated on single chip.

Title: Prodn. of mineral fodder or supplementary fodder as pieces - by compressing powdery mixt. of fodder components in roller press
Inventor: SCHINKEL OTTO DIPL ING
IPC: A23K40/20
Filed: 1991-02-02
Abstract: Mineral fodder and/or supplementary fodder in the form of pieces is made by pressing a homogeneous mixt. of different components of mineral fodder and/or supplementary fodder, using a roller press with 2 rollers rotating in opposite directions, with a nip between the rollers, to compress the powdery mixt. to pieces. Pref. the grain sizes of the fodder components are made similar before or after prepn. of the mixt. The press may have profiling, pref. circumferential, and may have grooved rollers, or may have troughed rollers to give the fodder as briquettes. A screw may be used to precompress the powder mixt. before the roller press. The pieces of fodder may be comminuted and opt. sieved after compression. ADVANTAGE - The process saves energy, and gives more storable pieces of fodder

Title: Program-controlled washing machine has laundry drum and pressure monitor to control fresh water supply - ensures consistent availability of sufficient washing soln. for spraying
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F33/02
Filed: 1992-08-21
Abstract: A program-controlled washing machine has a drum for the washing and a pressure monitor for controlling the fresh water supply. During the washing process, the washing is continuously sprayed with washing soln. and several spinning phases are executed for replacing the washing soln.. The spinning phases occurring during the washing process are triggered off via the pressure monitor when there is a failure to achieve a pre-set washing soln. level. When this level is not reached after the ending of a spinning phase, the water supply is switched on by the pressure monitor until the aforementioned level has been reached. ADVANTAGE - The machine ensures the availability of a sufficient amount of water for the spraying cycle, as well as regular interim spinning during the washing cycle.

Title: Mirror system with all radii concentric to common centre point - is completely free of coma, astigmatism and distortion, if no symmetry break is present
Inventor: GALLERT FRANK
IPC: G02B17/06
Filed: 1992-09-21
Abstract: The system characterises by its position the centre point of a shutter, with the curved image field also concentric to the centre point. The curvature radius of the image field is equal to the system focal length. In the light path sequence, a collector spherical mirror projects an intermediate/image spaced from its focal length. Then a divergent light impinges on a spherical dispersion mirror, which increases the light divergence. Then the light impinges again on a spherical collector mirror, reflecting the light onto a detector. By suitable solution of the mirror spacings and radii, the spherical abberation is removed. ADVANTAGE - Spherical abberation correction is carried out exclusively by spherical mirrors.

Title: Electronic retouching system for colour images in colour reproduction - provides colour intensity correction of selected points of stored colour image simulating effect of real retouching brush
Inventor: BEHRENDS ROLF
IPC: H04N1/46
Filed: 1992-09-30
Abstract: The retouching system uses a correction field containing at least one point element, displaced relative to the area of the image to be retouched via a marking device, with the corresponding coordinates being recorded. The digitalised colour values for the scanned original held in a memory are corrected via correction intensity values, at the recorded coordinate points, in dependence on the entered retouching effect, under visual control. The required colour retouching correction intensity distribution for the marking device correction field is stored prior to retouching, for determining the correction of each image point during retouching, with a max. or min. correction intensity selection allowing the effect of a real retouching brush to be simulated. USE - For image retouching in electronic reproduction.
